10 Claims.

My invention relates more particularly to the rings and ring holders of spinning and twisting machines.

It has heretofore been necessary to employ a difierent depth of ring for each particular range of counts or numbers of any fibrous materials to be spun or twisted, thus requiring the use of several sets of rings of diiferent depths to twist or spin fine or coarse counts. The traveler necessarily had to embrace both the top and bottom of the ring, but in changing from the spinning or twisting of a coarse count of yarn to a lighter count the weight of the traveler had to be changed to produce the proper tension of the yarn; and this resulted in making the traveler toowide to conform with the arc of the ring, or too narrow and long for stability or service. An object or my invention is to enable the production of yarn of various counts in a single composite ring structure.

Further objects are to facilitate the removal, substitution, and rearrangement of the ring elements relatively to the holder; to aii'ord a ring construction adapted to the more thorough hardening of the ring elements, and at a minimum expense in method, labor, and material; to adapt the ring elements for facile cleaning; to afford sufficient space intermediate the ring supports for the reception of a wick or the direct application of a lubricant; to enable the use of travelers of unusual hardness; to afifiord ample clearance or raceways for the travelers; to render possible the employment of travelers of the shape and style commoniy in use. Further objects of invention will appear from an examination of the drawing and following description.

To the above ends primarily my invention consists in such par s and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawing forming a part of this specification,

Figure l is a top plan View of a novel traveler support embodying my invention with a traveler thereon, showing parts broken away,

Figure '7, a diametrical section of a modified form of ring.

Like reference characters indicate like parts throughout the views.

As herein shown 20 represents a ring rail of common construction including spindle openings or ring sockets 22, one only of which is shown, into which extend the inner ends of one or more, in this instance three, holder or clamping screws 23, 24 and 25 threaded in the rail adapted to operate in the usual manner upon a split holder.

My device includes a ring holder 26 combining in a novel integral structure certain characteristics of a vertical ring of the solid type, and of a cast iron ring holder of the split type. My holder is annular, vertically elongated, and externally conforms to the particular diameter of the rail opening intended for its reception. It is provided externally with an intermediate annular shoulder 23 resting upon the rail and supporting the lower portion of the holder in the opening 22 through which it depends. The holder is composed or iron, steel, or other suitable metal, either forgings, castings or stampings.

Integral with the cylindrical interior face of the holder are a plurality of equally interspaced inwardly extending horizontal flap lips, ribs or projections 30 distributed from the top to the bottom edges of the holder, and in this instance tour in number. The holder is of the resilient split type, there being a vertical cross cut, slit, or opening 32 through the holder and projections.

Detachably supported by each projection is an annular ring 34 somewhat flattened or vertically elongated, with rounded upper and lower edges, and provided centrally of its exterior side with an annular slot 35 into which extends, as a sliding fit, the adjacent projection 30. The four rings function as tracks for ring travelers. The material of the rings is preferably of hardened steel, but iron, and metals forged, cast or stamped may be employed. The rings may be transversely circular. In Figure 7 they are so shown.

The rings are capable of relatively simple and inexpensive formation and superior hardness, since they may be formed from flat or transversely curved straight rods, each milled with a 1ongitudinal groove, then cut to desired lengths, bent, and sometimes welded, and finally hardened and polished. The relatively small cross sectional area of the ring material as Well as the absence of material formerly occupied by the slot facilitates the complete penetration of the heat throughout the ring mass in the hardening operation. The diameters of the final rings, which are diflferent in holders of markedly difierent diameters, are thus determined by the extent of the initially cut lengths.

The spaces intermediate the annular projections 30 are ample for the reception of lubricating wicks or for the lubricant itself.

In assembling it is convenient while the holder is resting expanded in its rail opening to initially loosely apply the rings 34 upon the respective projections 30. Then one of the screws 23, 24, or 25 may be tightened to finally contract the holder and hold the rings in rigid engagement with the annular projections. Thereafter, loosening the clamping screw permits the holder to expand and enables the rings to be detached, readjusted, or removed from the projection. Thus the removal of the rings for cleaning, substitution for wear, repair, or other purposes is easily efiected. In introducing rings of slightly larger diameter than usual into the holder due to variations due to the process of hardening, the latter, because of its split character, yields or expands to admit the ring, and the natural contraction of the holder is sufiicient to force the projections into the ring slots, so that little or no tightening of the screw is required.

The plurality of interspaced superposed rings in a single holder makes it possible to employ at will travelers of varying lengths, and thus in a single structure enables the spinning or twisting of both fine and coarse counts. In Figure 3 a vertical type traveler 38 is shown mounted upon the two upper rings. This traveler has the usual vertical shank 38, downwardly directed head 39 and upwardly directed foot to. In Figure l, a somewhat longer, and therefore heavier, vertical traveler 42 is shown engaging the uppermost ring and the second ring below. In Figure 5 a still longer and heavier vertical traveler 4.4 engages the topmost and lowermost rings. When a single ring is employed the uppermost ring only is used, and some form of the arched type of traveler d6, as shown in Figure 6, is preferably employed. In Figures 4, 5 and 6 the rings not in immediate ac tive use are shown to be temporarily removed from the holder 26, but such removal is optional.

Travelers of the vertical type are preferably applied to their rings 34 by inserting the latter between the head 39 and foot 40 of the traveler prior to applying both the rings to their projections30, and thereafter aifixing the rings to their respective projections. By this means the traveler structure is not subjected to the strain of forcing the head and foot of the traveler over pre viously fixed rings, and a traveler of unusual hardness or brittleness may be safely employed.

In place of rings 34, vertically elongated in transverse section, may be substituted rings 43, transversely circular in cross section, one of which is fragmentarily shown in Figure '7.

Without departing from the spirit of my invention other modes of applying the principle thereof may be employed instead of the ones explained, change being made as regards the construction herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
